the reset button code will have to be under the btnReset sub procedure Private Sub btnReset_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReset.Click txtLiters.Text = "" (other two buttons) End Sub

can you double click on the button in the design window so that windows writes the code for you? if not it would look something like this: Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnComput.Click also i would change the Me.Textbox1.Name to Me.txtLiters.Name this can also be done in the design window by changing the name in the properties window, you would just have to type txtLiters in the name property. the same should be done to Me.Textbox2.Name to Me.txtPints.Name Me.Textbox3.Name to Me.txtGallons.Name Me.Button1.Name to Me.btnCompute.Name Me.Button2.Name to Me.btnReset.Name for the liters input: Dim liters As Decimal 'liters input liters = txtLiters.Text to convert liters to pints, 1 liter is 2.113 pints so: txtPints.Text = (liters)*2.113 to convert liters to gallons, 1 liter is 0.264 pints you just have to format it like the pints example for the reset button you just have to initialize all text boxes with null strings so for liters it would look like: txtLiters.Text = "" the other two buttons would be coded the same
